DESCRIPTION

Census Block 2010 captures the value of both the 2010 Census Block and the 2010 Census Group.  A census block is the smallest geographical unit used by the U.S. Census Bureau.  A block group is a set of blocks sharing the same first digit of the four-digit block within a Census Tract.  For example, block group 3 within a particular Census Tract would include any blocks numbered between 301 and 399.  The first digit of this variable identifies the 2010 Census Block Group.  The 3 digits of this variable, taken as whole, identify the 2010 Census Block.

 

Eureka stores Census Block 2010 in the database and can parse Block Group from Block, if needed. This number is supplied by Geocoding. Volume II, Appendix A does not require it from vendor software.

UPDATE

Whenever Census Tract 2010 is changed, Census Block 2010 must be changed accordingly.

• If Census Tract 2010 is untracted ('999993' or '999996') then Census Block 2010 must be blank.

• If Census Tract 2010 is tracted and a Census Block 2010 tracted code is available (whether through geocoding, linking a tumor with a tracted address, or manual entry of a Census Block 2010 value) the available Census Block 2010 code should be used.

• However, if Census Tract 2010 is tracted but Census Block 2010 is not available, Census Block 2010 should be set to blank
